The particular bolt-action firearm herein 50 chosen for the illustration of the present invention is of the take-down type and includes three major components, namely a receiver 20, a barrel 2|, and a stock 22 all organized together in a manner as will more fully hereinafter appear.

The receiver 20 is cylindrically-contoured exteriorly and has its forward-end interiorly threaded for the threaded connection of the exteriorly-threaded rear-portion of the barrel 2i. Extending substantially throughout its length, the receiver 20 is formed with a downwardlyopeningbolt-receiving chamber 23 having its upper-half cylindrically-contoured to conform to the similarly-contoured upper-half of a reciprocating breech-bolt generally designated by the reference "character 24!. The said breech-bolt 24 is retained in place in the'bolt-receiving chamber 23 in the receiver 20 against downward displacement therefrom, by a bar-like mounting other toprovide a central-longitudinal channel plates 26 and 2'! of the mounting-member 25 to 28, by a rear spacing-block 29 anda front spacing-block 39. x

The upper portion of the rear spacing-131001429 projects above the upper surface ,of the sideform a head 35 which conforms in cross-sectional form to the transverse form of the bolt-receiving chamber 23 in the receiver 20. The head 3| of the spacing-block 29 is formed with a rearwardly-projecting coupling-extension 32 abutting against the rear-wall 33 of the receiver 20 and overhangs a forwardly-extending coupling-lip 34 extending forwardly from the lower portion or the said rear-wall 33, so that the said coupling? extension 32 and the said coupling-lip 34 serve to normally prevent the downward movement of the rear-portion of the mounting-member 25 from the bolt-receiving chamber 23 in the receiver 2 0. t

The rear spacing-block 29 of the mountingmember 25 is formed at its lower portion with a rearwardly-extending coupling-lip 35 which is adapted to removably hook-under, so to speak, a coupling-pin 35 extending transversely across the rear-portion of a longitudinally-extending upwardly-opening recess'3'l formed in the stock 22, before referred to. The said coupling-pin 36 thus forms a permanent feature of the said stock 22.

Returning now to the front spacing-block 30 of the bar-like mounting-member 25 it will be noted by reference to Figs. 3, 4, and 5 in particular that the said spacing-block is formed in its forward face with a forwardly-opening cylindrical coupling-socket 38 adapted to receive the cylindrically-contoured rear-end 39 of a coupling-screw 40 located mainly beneath the rear portion of the barrel 2| and extending in parallelism therewith.-

The said coupling-screw 40 is threadedly-inounted in a block-like stock attaching lug 4| depend-- ing from the rear portion of the barrel 2| and fixedly attached thereto by means of a dove-tail connection 42. The stock-attaching lug 4| just referred to, has threaded into it the threaded upper end of a stock-attaching screw 43 which'extends upwardly from the under-face of the stock 22 through an escutcheon 44 mounted in the said stock 22, and serves to secure the forward portion of the said stockto the barrel 2| and hence to the receiver 20 and its associated parts.

The breech-bolt 24 is formed adjacent its rearend with I a transverse bearing-passage 45 in which is adapted to turn the cyliridrically-cohtoured shank 46 of a bolt-operating handle generally designated by the reference character 47 and including an L-shaped arm 48 carrying at its distal end an operating-knob 39. i

As above referred to the shank of the boltoperating handle 41 is, generally speaking, cylindrically-contoured but is provided with numerous cuts, notches, and projections including two clearance notches 50 and 5| respectively located in line with the side-plates 26 and 21 of the barlike mounting-member 25 before referred to. Intermediate the clearance notches 59 and just referred to, the shank 46 is formed with a forwardly-opcning. notch 52, the rear-wall of which constitutes a latch-engaging abutment 53 for the purpose as will hereinafter appear. Transversely in line with the notch 52 just referred to, the intermediate portion of the shank 46 is formed with a rearwardlyand downwardly-opening notch 54, the rearwardly-facing end-wall of which constitutes a limiting-abutment 55 which serves in a manner as will herein appear, to limit the rearward swinging movement of the bolt-operating handle 5?.

The shank 46 of the bolt-operating handle 41 is.

also provided with a transverse groove 56 extending from'front to rear across the upper portion of the saidshank 46 and having a bottom-wall which constitutes a disconnecting-cam 5'! serving in a manner as will hereinafterappear to render the firing-mechanism temporarily inoperative when the breechbolt is unlocked, by operatively disconnecting a trigger 58 from a sear 59. The shank 4B of the handle 41 is further provided in its upper portion with a firing-pin-clearance groove 60 extending from front to rear and accommodating a reciprocating firing-plunger or -member 6| which passes from front to rear therethrou'gh.

The firing-plunger 6| above referred to, reciprocates in an axial-passage 62 formed in the breech-bolt 24 and is formed at its forward-end with a firing-point adapted to impinge against and fire a cartridge such as 64 when the-same is in the cartridge-chamber 65 formed in the rearend of the barrel 2|, in the usual manner of firearms. In its upper rear-portion the said firingplunger 6! is formed with a forwardly-facing cocking-abutment 66 which is releasably engaged by a sear-nose 61 located at the forward-end of the sear 59 which latter is mounted for pivotal movement upon a transverse pin 68 extending across a longitudinal slot I59 formed in the upper portion of the head 3| of the rear spacing-block 29 as is especially well shown in Fig. 3. The rearwardly-extending portion of the sear 59 is pressed upwardly by a helical sear-spring 10 seated in an upwardly-opening spring-pocket ll formed in the said head 3|. The sear-spring 10 as thus arranged exerts a yielding effort to hold the sear-nose 61 of the sear 59 downwardly in the path of movement of the cocking-shoulder 66 of the firing-plunger 6 l At a point intermediate the pin 68 and the sear-nose 61 the. sear 59 is formed with a downwardly-facing actuating-abutment 12 which is adapted to be engaged by the upper end of the body-portion 13 of a transmitting-member generally designated by the reference character 14/ The said transmitting-member 14 also includes a forwardly-extending finger I5 having its forward end bevelled to provide a forwardly and upwardly-sloping cam surface 16 which is engageable by the disconnecting-cam '51 of the shank 46 of the bolt-operating handle 41. The forwardlyextending finger 15 just referred to, is offset laterally out of the plane of the body-portion 13 and is integrally united therewith by a transverselyextending web 11.

The body-portion 13 of the transmitting-member 14 is mounted for both vertical reciprocating movement and rocking movement in a forwardlyopening vertical groove 18 formed in the rear spacing-block 29 and intersecting the upwardlybpening slot 69 therein as is particularly well shown in Fig. 3 of the drawings. Mounted in the rear spacing-block 29 and extending through a vertical slot 19 in the body-portion 13 of the transmitting-member 14 is a pin 88 upon which the said transmitting-member is free to rock and with respect to which the said transmittingmember is free for limited vertical movement.

Mounted in the forwardly-opening vertical groove 18 in the rear spacing-block 29 is a helical spring 8| which exerts a constant but yielding effort to'hold the transmitting-member 14 in its lowermost position and at the limit of its clockwise pivotal movement as viewed in the drawings. The lower-end of the body-portion 13 of the transmitting-member 14 is held by the spring 8| in close proximity, if not in actual contact with the upper end of the trigger 58 which is provided with a clearance-passage 82 for the purpose as" will hereinafter appear. The trigger 58 is mounted for pivotal movement upon a transverse-pin 83 extending transversely across the stock 22.-

The said trigger 58 extends upwardly into a vertical passage 84 formed in the stock 22 and into the upper end of which passage the lower end of the body-portion 13 of the transmitting-member 14 extends. v

Returning now to the bolt-operating handle 41, it will be noted that the formation of the clearance notches 58 and 5I in the shank 46 of the said bolt-operating handle, results respectively in the formation of locking-noses 85 and 86 which when turned in their unlocking positions, are adapted to ride over the upper edges respectively of the side-plates 26 and 21 of the bar-like mounting-member 25. When the breech-bolt is in its forward position and the operating-knob 49 of the bolt-operating handle 41 is swung to the limit of its forward movement the said locking-noses 85 and 86 are respectively adapted to enter locking-notches 81 and. 88 respectively formed in the said side-plates 26 and 21. I

When the operating-knob 49 of the bolt-operating handle 41', is drawn rearwardly such.

movement is limited by the engagement of the limiting-abutment on the shank 46 with a forwardly-facing limiting-abutment 89 forming a feature of the breech-bolt 24. When the bolthandle is swung as just described toengage its limiting-abutment 55 with the limiting-abutment 89," the latch-engaging abutment 83 thereof is also brought intoposition to be engaged by the rearendof a pivotal holt-handle-locking member 98.

The said member98 is mounted for rocking move- I ment in a vertical plane in'a verticallyrextending groove 9| formed in the rear depending portion of the breech-bolt 24 and is pivoted in the said groove upona.transverse-pin 92 carried by the 7 said breech-bolt.

Yieldingly urgingthe member 98 to turn in a clockwise direction so as to engage its:rear portion with the latch-engagjing abutment 53, ofthe shank 46, is a helical spring '93 having its upper end seated in a shal bolt-handle-locking which jacent portion of the breeclij-bolt 24. The rear 'end of the detent-plunger II5 slopes-forwardlyltripping-nose 95 which is adapted to engage a tripping-nose 96 formed at' the rear-end of a pivotal cartridge cut-off 91 hung upon a pivotpin 98 extending transversely between the two side-plates 26 and 21 of the mounting-member 25. At its forward end the cartridge cut-off 91 is formed with a head 99 the upper portion of which is adapted to rock upwardly into a releasing groove I88 formed in the under-face of the breech-bolt 24 and registerable with the upper portion of the said head when the said breechbolt is in its forward or fully closed position and for a purpose as will more fully hereinafter appear.

Projecting downwardly from thehead 99 of the cartridge cut-off 91 are three (more or less) cartridge-stops IN the rearmost one of which is adapted to be engaged by and releasably hold the foremost cartridge I82 of a column of cartridges emerging from a tubular-magazine I83 under the urge of a magazine-follower I84 and a magazinespring I (Fig. 3).

The said tubular-magazine I83 is normally lo cated within a tubular-magazine-housing I86 extending downwardly and rearwardly from adjacent the cartridge cut-off 91, through the stock 22 as is shown in the drawings,

Returning now to the firing-plunger 6| it will be noted by reference to Fig. 3 in particular, that the rear-portion of the said firing-plunger is provided with a rearwardly-opening spring-receiving chamber I81 receiving the forward portion and, on occasion, the entire length of a helical firingspring I88. The forward end of the firing-spring I88 thrusts against the front-end wall of the spring-receiving chamber I81 and thrusts at its rear-end against a' thrust-shoulder I890. formed upon a guide-rod I89 at the junction of the relatively-large rear head-portion II8 thereof and the vertical. groove 18 therein. The interfitting of the boss H2 and socket II3 serves to support the rear-end of the guide-rod I89 in alignment with the spring-chamber I81 in the firing-pin 6|.

For the purpose of yieldingly holding the boltoper'ating handle in its breech-bolt-locking position, the transverse bearing-opening 45 in the breech-bolt 24 hasintersecting its forward periphery adjacent the left sideof the said breechbolt, a forwardly-extending plunger-receiving recess H4 in which is adapted'to reciprocate a detent-plunger H5 which is pressed rearwardly by a helical spring II6 housed in the forward portion of the 'saidplunger-receiving.recess I I4, as is particularly wellshown in 12. In its underside, the detent-plunger I I5 is formed with a limiting-notch II1 substantially corresponding in length to the desired length ofthe reciprocating inovement of the said detent-plunger and across extends a stop-pin I I8 mounted in the adand-upwardly and is adapted 'to engage the u'pper wall 5|a of the clearance-notch 5| in the shank 46 of the bolt-operating handle 41 to yieldingly hold the said bolt-operating handle in its breechbolt-locking position.

In the manner above described, the bolt-operating handle 41 is sufficiently restrained against movement out of its breech-bolt-locking position to guard against the inadvertent un-.

locking of the breech-bolt by substantially all but intentionally-applied forces.

For the purpose of making clear the operation of the bolt-action firearm herein chosen for illustration of the present invention let it be assumed that the parts are in the positions in which they are shown particularly well in Figs. 1, 2 and 3 which indicate conditions prevailing after a cartridge has been fired by the forward movement of the firing-plunger 6| which has been' position indicated by broken lines A in Fig. 1,

the shank 46 of the said bolt-operating handle will be turned in a clockwise direction into the position in which it is indicated in Fig. 4. This turning of 'the shank 46 as just described, will engage the limiting-abutment 55 thereof with the limiting-abutment 89 of the breech-bolt 24 to thus limit the described turning movement of the said shank 46. The described turning movement of the shank 46 will also cause the disconnecting-cam 51 thereof to act through the finger of the transmitting-member "and rock the latter into the position in which it is .ndicated by full lines in Fig. 18 thereby opera- ;ively-disconnecting the sear 59 from the trigger 58 so that when the firing-plunger 6| is cooked t cannot be released until such time as the bolt- )perating handle 41 is in its bolt-locking posi- '.1on.

In addition to the above described efiect of he initial clockwise turning movement of the Lhank 46 of the bolt-operating handle 41, they :aid turning movement swings the locking-noses l5 and 86 out of their complemental lockingiotches 87 and 88 in the side-plate 26 and 21 'espectively of the mounting-member 25, with he result that the breech-bolt 24 and the parts arried thereby are free for being retired rearvardly.

After the bolt-operating handle 41 has been umed as described in the position in which it is ndicated by'the broken lines A in Fig. 1 to efiect he operations above described, a continued rearlard. draft exerted upon the operating-knob 49 vill bodily shift the said bolt-operating handle I rearwardly into the position in which it is ndioated' by the brokenlines B in Fig.- 1 so that he parts will assume the positions in which they .re shown in Fig. 4 of the drawings in which it rill be noted that the breech-bolt 24 is retired o, themaximum of its rearward movement and hat the sear-nose 61 is located relatively-fob rardly of the cocking-shoulder 66 of the firinglunger 6|. .A." has been before noted and as rill be seen by reference to Fig.4 the shank. 46

of the bolt-operatinghandle 47 and hence the entire handle is locked against return swinging movement by the engagement of the rear edge of the bolt-handle-locking member 90 with the latch-engaging abutment 53 of the said shank 4'6.

The retraction of the breech-bolt 24 above de-' scribed will effect 'the extraction of the cartridge" case of the previously-fired cartridge in the cartridge-chamber 65 of the barrel 2| in the usual manner of firearms.

If now a forward thrust is exerted upon the. operating-knob 49 of the bolt-operating handle 41 the said bolt-operating handle will be prevented from turning in a counterclockwise direction by the bolt-handle-locking member 90, with the result that the said thrust upon the operating-knob 49 will become effective to forwardly-move the breech-bolt 24' and theparts carried thereby. As the said breechbolt 24 moves forwardly the firing-plunger 6| will also move forwardly, but only for a relatively-slight distance until its cocking-shoulder 66 engages with the sear-nose 61 of thesear 69 whereupon the further forward movemfentof 'the said firingplunger'wil l be checked until released in a man-.

ner as will be hereinafter described.

In its forward travel as above described the front face of the breech-bolt 24 will engage the rear face of the cartridge 64 and move the said cartridge forwardly and upwardly from the position in which it is shown in Figs. 3 and 4 toward the position in which, it is shown in Fig. 5,

for final and full seating in the cartridge-chamber 65..

At about the time during its forward travel from the position in which it is shown in Fig. 4 that it reaches the position shown in Fig. 5, the breech-bolt 24 will have shifted the bolt-handlelocking member 90 sufliciently forwardly to engage its tripping-nose 95 with the rearwardlyprojecting tripping-nose 96 of. the cartridge cutoff 9] with the effect, as the said breech-bolt and the said member 90 continue to' move forwardly;

of rocking the said member 98 about its pin 92 in a counterclockwise direction against the tension ofthe spring 93. This rocking movement will completely disengage the rear end of the said member 90 from the'latch-engag'ing abutment 53 of the shank 46 of the bolt-operating handle-41. This release of the shank 46 as just referred to occurs just as the said shank is sulficiently far' forwardly for the registration of its locking-noses 85 and 86 with the locking-notches 81 and 88 respectively in the side-plates 26 and 21 of the mounting-member 25. Continued forward thrust upon the operating-knob 49 .will

tion shown in full lines. in the. same figure, thus rotating the'shank- 46 in a counterclockwise. di-

rection. The described movement will cause the v entry of the locking-noses 85 and 86 of the shank -46.- into the locking-notches 81' and 88 before 4 referred to, to thereby firmly lock the breechbolt in its breech-closing position. The. final counterclockwise turning movement of the shank 46 of the above operating-handle 41 as just described, will cause the disconnecting-cam 51 of the said shank to turn and thereby permit the transmitting member 14, under theu'rge of the spring 8|, to rock in a clockwise direction about body-portion 13 will be located beneath the actuating-abutment 12 of the sear 59, in readiness to its pivot-pin ,88 so that the upper edge of its ward movement of the breech-bolt 24 will bring the releasing groove I00 therein into full registration with the upper portion of the head 99 of the said cartridge cut-01f, thereby permitting the latter to turn in a counterclockwise direction .to release the foremost cartridge "32 of the col-' umn of cartridges, for movement into aflposition beneath the substantially-closed forward end of the breech-bolt24, preparatory to being fed into the cartridge chamber 65 when the breech-bolt is again withdrawn rearwardly and again moved forwardly in another cycle of the operation of the firearm. The parts'will now have assumed locking-notches 81 and 88 in the side-plates 26 and '21 of the mounting-member 25, the said shank and the entire bolt-operating handle willbe releasably held in this position by the coaction of the sloping rearward end of the detent-plunger H5 with the now-sloping upper wall 5la of the clearance-notch 5| in the shank 46, as is clearly shown in Fig. 12. r

From the foregoing, it will be seen that by means of the bolt-handle-locking member 90 or its equivalent, the bolt-operating handle 41, when once retired rearwardly and upwardly to unlock the breech-bolt 24, is restrained in such position, so that when it is desired to again close the breech-bolt, a forward thrust exerted on the knob 49 of the saidhandle 21 will not turn the same to possibly cause serious jamming, friction or wear,'but will cause the straight-line forward travel of the said breech-bolt until the same is closed, or substantially closed, prepara- -tory to being locked, whereupon the said bolthandle-locking member is automatically released at the proper time to permit the'shank (l6 to be turned as required for locking the said breech-bolt.

' The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
